I have a Macbook Pro (Retina 15 inch end 2013) with OS X El Capitan 10.11.1. I have Bootcamp on it to run Windows 7, always using it without any problem. I wanted more space on the Bootcamp partition so I decided to resize the Macintosh HD partition to make some more space (+10 GB) for the Bootcamp partition.

When I made the Macintosh HD partition 10 GB bigger I've tried to reboot into Windows with Bootcamp but unfortunately the error 'No bootable device, press any key' appears.

I can still see Windows bootcamp in the startup disk of system preferences, but just can't boot into Windows anymore.

Here are some messages I've got by Terminal;

MBP-van-Daniel:~ daniel$ diskutil list

And some more

I've tried some suggested solutions I've read on the web but unfortunately without result. I think I have to restore the MBR using fdisk but how do I do that? I'm not very familiar with terminal

Sorry about my English. I mean I've made the Macintosh HD partition 10 GB smaller so I later could make in Windows the Bootcamp partition bigger. When I made the Macintosh partition smaller, Disk Utility made a new unnamed partition of that 10 GB. This means there were a total of 5 partitions. In Terminal the BOOTCAMP partition was situated on number 5 and the unnamed new empty partition on number 4. I think the problem is that the system only can boot the first 4 partitions. I've deleted the new empty partition again and set the Macintosh HD at its original size, so BOOTCAMP is now again on #4;

In my first post I had deleted the 10 GB empty partition already. I've installed Refind and after using the reinit and write command I'm now able to choose every time I start up my macbook, several options to boot like Macintosh, Windows and other devices. Now I can boot again into Windows. The only problem is that if I make Macintosh HD partition smaller, a new partition is created that comes at #4 so that BOOTCAMP moves to #5.
